Standards for Bunker Fuels)
✔ ISO 8217 grade (Marine Fuel
Quality Standards)
✔ MARPOL Annex VI Compliance
Why Choose an Independent Bunker
Quantity Survey?
✔ Prevents financial loss –
Confirms the actual quantity delivered, avoiding overcharges.
✔ Ensures representative sampling
– Verifies fuel quality with proper sampling methods.
✔ Reduces disputes – Immediate
resolution of discrepancies during bunkering.
✔ Enhances regulatory compliance
– Meets MPA Singapore SS648:2024, ISO 8217:2024, and global standards.
💡 With fuel costs
increasing, even minor discrepancies in bunker quantity can have a significant
financial impact. Independent verification ensures accuracy and prevents costly
claims.
Seahawk Services BQS Process
Our certified BQS surveyors oversee the entire bunker operation,
ensuring precise quantity measurements, compliance with SS648:2024 mass flow
metering requirements, and accurate fuel sampling.
📌 Pre-Bunkering
Procedures
- Communicate
with vessels, suppliers, and agents to coordinate a smooth
operation.
- Review fuel
delivery details – including fuel grades, delivery method, and receiving vessel
requirements.
- Verify the use
of SS648:2024-compliant Mass Flow Meter (MFM) systems, ensuring
proper calibration.
- Confirm
sampling procedures – ensuring compliance with ISO
8217:2024, MARPOL Annex VI, and MPA guidelines.
🛢 Fuel Quantity
Measurement (SS648:2024 Compliance)
- Monitor bunker
delivery using approved mass flow metering systems in
SS648:2024-compliant ports.
- Conduct manual
tank measurements before and after bunkering when
MFM is unavailable.
- Verify barge,
truck, or terminal fuel quantities to detect discrepancies.
- Oversee the
entire bunker operation, immediately addressing any
quantity disputes.
- Perform ROB
(Remaining On Board) inspections to account for undelivered fuel.
🧪 Fuel Quality
Verification (ISO 8217:2024 Standards)
- Ensure proper
sample collection methods – including drip, continuous,
or spot sampling.
- Secure fuel
samples with tamper-proof seals and documentation.
- Verify
compliance with ISO 8217 grade fuel specifications as required by customer, including:
- Sulfur content
& emissions compliance
- Viscosity
& ignition properties
- Catfine levels
for engine protection
- Water,
sediment, and contamination levels
- Cold flow
properties (pour point, wax appearance/disappearance temperature, CFPP)
- Verify
supplier-provided fuel samples to ensure alignment with
delivered fuel.
